flexible interval put back

[Biobabar]

Hello !
I'm using 1.8.3 zabbix agent for windows
I want verify if my directory is empty.
My key is : system.run[dir c:\EDI_PLAN\CDE\ | find "fichier(s)"]
Type of information : Text
Update interval (in sec) : 0
Flexible intervals (sec) : 7200 sec at 1-5,05:30-19:35

I want a reel flexible intervals between 07:30-21:35 but with my UTC +2, it does not work properly.

The answer is good but, the real problem, it's I have my first information at 8h30 and not 7h30...

Where is the error ??

I add I have already another key
key : system.run[dir c:\EDI_PLAN\BL\ | find "fichier(s)"]
Type of information : Text
Update interval (in sec) : 0
Flexible intervals (sec) : 7200 sec at 1-5,06:30-20:35

Here, it's a good return at a good time !
first return--> 31 Mar 2011 08:31:31 0 fichier(s)

Why for the Flexible intervals "7200 sec at 1-5,05:30-19:35" the first return is at 08:30 too?

Thank you for your help

For one, I have :
Flexible intervals (sec) : 7200 sec at 1-5,06:30-20:35
with result :
from 8h30 to 22h30 with 2h intervals
(GOOD)

And another :
Flexible intervals (sec) : 7200 sec at 1-5,05:30-19:35
with result :
from 8h30 to 20h30 with 2h intervals

I don't understand...

some test with different "flexible intervals":
it's start at :

logically --> real
5:30 --> 8:30
5:00 --> 8:30
4:30 --> 7:30
4:00 --> 7:30
3:30 --> 6:30
3:00 --> 6:30
2:30 --> 5:30
2:00 --> 5:30

I need to start at 7:30... So I will start at 4:30
But it's very strange
